Liverpool boss Brendan Rodgers was also incensed by Costa’s actions, which could see the Chelsea striker banned from Saturday’s title crunch with Manchester City if the FA decide to take retrospective action.

But Mourinho rounded on Redknapp, after hearing what had been said on Sky’s coverage of Chelsea’s victory to reach Wembley.

The Blues' boss, who is already awaiting an FA hearing after claiming Chelsea were the victims of a referee campaign, said: “I don’t know what you understand by a stamp.

“Maybe you are already influenced by the campaign on the television with the certain pundits saying that Costa has crimes - they must be nuts, the guy who says that.

“Sky calls it a crime. I have to say that he goes to the ball, he chases it, the opponent goes to the floor and he puts his foot there when he is looking at the ball.

“It is a great campaign.

"We know how much that pundit loves Chelsea. So you are sitting there, you are very well paid and you are a manager putting their ass on the bench.

“These guys have a good seat, earning a lot of money, no pressure, they are never wrong. They have to be fair and they have to be honest.”

Mourinho does mean Redknapp, but refused to name him publicly.

He added: “I don’t know his name because when I see it I switch off the television.”

Rodgers, whose side were unlucky to lose after a pulsating two-legged semi final, was unhappy with Costa’s stamp and also claimed he could have been punished for another stamp on defender Martin Skrtel.

“He’s an outstanding player, an outstanding footballer. He obviously has this edge to him. We see the TV incidents, the two that he had. The one with Emre Can... that was poor I felt.

“He could easily hurdle over the young player. But he directs his studs right onto his ankle, which could have been nasty.

“And the one with Srktel, again, there’s no need to do it. That’s the sad thing. He’s a top-class player. And he’s clever enough that the officials don’t see it. But it’s poor by him because he’s an outstanding player, a top player, and he doesn’t need to do it.”

That led to Mourinho launching into a counter-attack on Rodgers, who worked under him as a youth coach at Chelsea early in his career.

The Special One said: “We are very different persons. We are different. Maybe he learned from me, maybe he didn’t.

"I could speak about Skrtel and I don’t. He speaks about Courtois and forgets Mignolet. He speaks about my keeper but when I do I speak about him.

“To say Courtois played fantastic, I could say the same about Mignolet. We have different profiles, he is a fantastic manager but we are different persons.”

So, Chelsea could be without Costa against Man City for disciplinary reasons and also face fitness worries - Cesc Fabregas limped off with a hamstring problem, Filipe Luis suffered a calf injury and goal hero Bratislava Ivanovic also has a cut foot.
